Cardiac arrest outcomes vary widely between out-of-hospital and in-hospital events, depending on timing, the first heart rhythm, and whether help is started immediately. On this page, you’ll see how bystander CPR, dispatcher-assisted guidance, and rapid AED use can improve survival. We also break down differences by location, such as urban versus rural, and by patient group, including adults and children.
Key Takeaways
- Public AED use by bystanders before EMS arrival increases OHCA survival to 67% in shockable rhythms per 2022 Japanese registry

- AED-equipped public sites OHCA survival 54.2% versus 9.3% non-equipped locations 2021 CARES
- Bystander CPR in OHCA increases survival to discharge by 2.8 times (from 7% to 19.6%) per 2022 AHA
- Dispatcher-assisted bystander CPR triples survival from 5.6% to 17.7% in unwitnessed OHCA 2021 study
- Bystander CPR in public OHCA yields 45% survival if AED also used versus 15% CPR alone Japan 2020
- In-hospital cardiac arrest (IHCA) survival to discharge is 25.8% per 2022 AHA Get With The Guidelines
- Shockable rhythm IHCA survival 38.9% versus 11.7% asystole/PEA in US 2021 registry
- IHCA in ICU survival to discharge 22.4% versus 29.1% in general wards per 2019 study
- In the United States, the overall survival to hospital discharge rate for out-of-hospital cardiac arrest (OHCA) treated with CPR is approximately 9.1% based on 2021 CARES data
- Shockable initial rhythm in OHCA leads to a survival rate of 29.7% to hospital discharge compared to 1.8% for non-shockable rhythms per 2022 AHA report
- In urban areas, OHCA survival to discharge is 11.2% versus 6.8% in rural areas according to 2019 ROC registry analysis
- Pediatric OHCA survival to discharge 9.2% overall lower than adults per 2022 AHA
- Infant (<1 year) CPR survival 5.6% versus 12.4% children 1-12 in US 2021 CARES
- Bystander CPR in pediatric OHCA survival 15.5% vs 4.5% no bystander per ROC 2020
Bystander CPR and rapid AED use dramatically boost cardiac arrest survival, especially for shockable and witnessed cases.
